The list of RQL keywords has operator exists(), which can be used under WHERE, though there are no documentation on it.
My understanding, that it allows filtering documents where a specified field exists.
E.g.
from Records where exists(Amount)
But how to negate exists() in order to get documents where the field DOESN'T exist?
An intuitive modification of the RQL above doesn't compile:
from Records where not exists(Amount)
